Three questions usually come up in discussion on prices:
1. Are Sony prices higher than other major brands, when comparing like for like?
2. Are prices in general higher than they were in the past (adjusted for inflation)?
The answer to both these questions is unambiguously no.
3. Are prices 'too high' by some objective measure?
I don't know how to answer that. A different way of asking the same thing is, "are camera and lens manufacturers including a higher profit margin than other comparable products, like other consumer electronics or whatever?"
The answer to that question is also probably no, but I'm sure there will be plenty of tedious ranting about corporate greed, as this topic always generates, and lots of strategic business 'advice' from armchair experts and keyboard warriors. If someone can provide some actual data on the topic rather than opinions then that would be interesting.
Probably more than one person will illuminate the discussion with, "the price is what consumers are willing to pay" - I've said it now so you don't have to.
